Syncdocs deletes local folders

I have accidentally deleted some folders from my Google Drive through my browser and the next morning I’ve realized that those folders had been deleted from my local google docs too. Moreover, I couldn’t find them in my recycle bin. Is there a way to setup syncdocs to backup only my local files instead of sync them ? Is there a way to redirect any deletions made by syncdocs program to the recycle bin ? What is the best practice to avoid something like this, from happening again ?

Due to the problem I've described in my previous post, I've temporarily disabled syncdocs application. I want to make a fresh start and I need to know:
Is there a way to reset the syncdocs settings without reinstalling the application ?
In order to do this, do I also need to delete all the files from my Google Drive ?

I am using the syncdocs portable application (registered). Yesterday I have noticed that syncdocs has deleted 3 files from various folders. It is not the first time that this is happening and I am wondering how is this possible, since the option "Sync renames, moves and deletions (do a full sync)” was not checked! I don’t want syncdocs to mess up with my local files. Is it possible to get syncdocs application to work as a real backup tool ? Take for example the echo option in microsoft synctoy application. All files from the desired folder are copied to the target folder (including moves, deletions, renames etc). It’s seems that syncdocs is not working properly as a backup application.

The files were deleted locally. I don’t want syncdocs messing around with my local files (the option "Sync renames, moves and deletions - do a full sync” was not checked). I just want syncdocs to work as a reliable backup tool and backup my local files onto my google drive (like the echo option in microsoft synctoy application. All files from the desired folder are copied to the target folder including moves, deletions, renames etc). Is it possible for syncdocs to do just that ? Because I have the impression that syncdocs is not working properly as a backup application.
